第二部分　英语知识运用(共两节， 满分45分)
第一节　单项填空(共15小题；每小题1分，满分15分)
从A、B、C、D四个选项中，选出可以填入空白处的最佳选项。
21．―Would you like to watch the basketball match with me this evening?
―　　　　.I like basketball very much.
A．I’d love to　　　　　 B．Not
C．I wouldn’t go
D．Thank you all the same
解析：选A。本题考查交际用语。根据对话的语境，A正确，意思是“我也想去”。
22．Because of the recent bad weather，the work is several weeks behind　　　　.
A．situation
C．insurance
D．schedule
解析：选D。考查名词辨析。句意为：由于最近天气不好，工作延误了几周。behind schedule晚点，落后于预计时间。
23．Put on your coat！I　　　　you down to the doctor.
C．have taken
D．am taking
解析：选D。考查时态。现在进行时有时也用来表示按计划或安排即将发生的动作。根据题意应选D项。
24．―How did your father　　　　smoking?
―The doctor told him to do so，and he took the advice.
A．give in
B．bring in
C．give up
D．bring up
解析：选C。考查短语辨析。give up放弃，符合句意：医生叮嘱他戒烟，他接受了这一忠告。give in投降，让步；bring in引进；bring up养育，提出。
25．I haven’t seen Ann for　　　　long that I’ve forgotten what she looks like.
解析：选C。句意为“我那么久没见安了以至于我都忘了她长什么样”。such...that结构中such后接名词，so...that结构中so后接形容词或副词，而题干中的long为副词，故C正确。
26．(2011年玉溪高一检测)If you stand by the windon，you will get a better　　　　of the sea.
B．scenery
解析：选D。考查名词辨析。句意为：如果你站在窗边，会对大海一览无余。get a good view of sth.为固定短语，意为“对……一览无余”。scene意为“场面，场景”；scenery为“风景”的总称；sight常用复数形式表示“人文景观”；view指从某一角度看到的风景。所以选D。
27．I was about to tell him the secret　　　　someone patted me on the shoulder.
解析：选D。考查be about to do...when...结构。句意为：我就要告诉他这个秘密，这时有人拍了一下我的肩。be about to do...when...表示“就要做某事，这时……”，为一习惯搭配，故选D项。
28．Lily got up at 6 o’clock　　　　，but she realized it was Sunday as soon as she prepared her school bag.
A．as possible
B．as usual
C．at present
D．at last
解析：选B。as possible“尽可能地……”；as usual“照常，跟往常一样”；at present“现在”；at last“最终”。根据句意“Lily跟往常一样6点起床，但是当她准备书包的时候她才意识到是星期天。”可知，应选B项。
29．―When was it that he　　　　to lend you some money?
―After he talked with his father，he told me that he could lend me money.
A．gave up
B．made up his mind
C．took his mind
D．changed his mind
解析：选D。由答语可知，他通过跟父亲谈话之后，才改变主意，答应借钱给“我”，故change one’s mind “某人改变主意”符合语境。give up“放弃”；make up one’s mind“下定决心”；无take one’s mind结构。
30．He is so kind a person that he takes a friendly attitude　　　　us.
解析：选C。take a friendly attitude to/toward sb.对某人采取友好的态度。
31．―Have you　　　　him to give up the job?
―Yes，I have.But he doesn’t listen to me.
A．persuaded
B．suggested
D．advised
解析：选D。由答语But he doesn’t listen to me推知，没有说服他放弃那份工作，故排除B项；suggest和agree后不能接不定式的复合结构。
32．They knew her very well.They had seen her　　　　up from childhood.
C．growing
D．to grow
解析：选A。句意为：他们对她非常了解。他们看着她从儿童时代长大。在see sb.do sth.句型中，省略to的动词不定式表示整个过程。
33．Lily’s fond of　　　　travelling and she always keeps　　　　travel journal of what she does each day during her trip.
A．the；the
解析：选D。Lilly很喜欢旅行，她总是写旅行日记来记录在旅行的每一天干了些什么。travelling此处是抽象性名词，前面不用冠词；keep a journal of写日记记录……。
34．―Why not join us in the game?
―I’d love to，but mother insists that I　　　　all my homework first.
B．will finish
C．must finish
D．have finished
解析：选A。答语意为：我也想和你们玩游戏，但妈妈非要我先把作业做好。insist后跟that从句作宾语，从句谓语动词用“should＋动词原形”表示虚拟语气，should可省略。
35．Being a　　　　person，Aunt Li wouldn’t let anyone or any difficulty stop her.
A．stubborn
B．reliable
C．determined
D．concerned
解析：选C。根据语境“李阿姨绝不会让任何人或者任何困难难住她”可知，她是一个意志坚定的(determined)人。

I’m lying on my back in my grandfather’s orchard(果园)，looking up at the branches above me.It is one of the last days of summer.Already the days are shorter and the nights are cooler.Some kinds of apples are already ripe(成熟的).Others will be ready to pick soon.I think of my grandmother’s apple pie，and how I used to make it with her.She died last year，before the apple harvest，and I have not had her pie since.I really miss her.I hear bees busily humming about，visiting the late summer flowers.The gentle hum of their wings nearly sends me to sleep.
The sky is as blue as my grandfather’s eyes.Above me，big white clouds race across the sky like pieces of cotton blowing in the w ind.School starts in another week，and time seems to have slowed down.
“Sophie！”calls my
grandfather.“Is that you？”I stand up，take his hand，and tell him all about my day as we walk through the orchard.We talk about apples，and bees，and Grandma.He tells me that he misses her too.
He puts his rough，brown farmer’s hand around my shoulder and pulls me close.“You know，Sophie，”he says，“I spent the morning in the attic(阁楼)，and you’ll never guess what I found.It’s the recipe(烹饪法) for Grandma’s apple pie.I used to help her make it sometimes.I can’t do it all alone，but you used to help her too.Maybe between the two of us，we ca n work it out.Want to try？”
“But it won’t be the same without Grandma，” I tell him.
“That’s true，”he says，“but nothing_is_the_same_without_Grandma.Still，I don’t think that she would want us never to have another apple pie.What do you say？” I nod yes，and we walk towards home...towards an afternoon in the farmhouse kitchen，making Grandma’s famous apple pie.

Do you want a bit of an adventure？Would you like to discover all the corners of the UK，or travel abroad？Maybe you have never tried the motorhome(旅宿车) lifestyle before.Well，read this article and you will know why a motorhome is a good choice.
Nothing is better than a motorhome.It has so many uses that it is considered the most versatile vehicle(交通工具) and it is also very comfortable.If you are thinking about hiring a motorhome this summer，then the best advice is to book it early，especially if you are considering the school holidays.The motorhome hire service is very seasonal and motorhome hire companies will never have extra vehicles available in the summer months.
There are a lot of companies throughout the UK，and some of the big ones have motorhomes spread all over the country.At present，the largest network for motorhome hire is provided by Motorhome which is based in Cambridge.If you are in the UK，you may phone 9 for details of its motorhome hire information.Motorholme has a network of over 500 vehicles all over England，Scotland and Wales.
Most people wishing to hire a motorhome are families that are looking for an alternative(替代品) to a European package holiday，especially as flying now
has become more expensive，and is considered to be environmentally unfriendly.There is no doubt that the idea of noMfly holidays is going to become more popular as fewer people think it is safe to fly.This explains why more and more people are choosing to hire a motorhome for their holidays.

Everyone has probably seen a movie or two about robots going against man.As a kid it was interesting，but not a reality.But today，when we look at how far scientists have come，it’s not just a funny thought but a real possibility.
Honda has already created a robot with eyes，legs，arms and hands and it can act just like a person.There_is_no_end_to_what_a_robot_could_do_in_the_future.Just think what we can do in twenty to thirty years.We’re dealing with almost an entire new species of humanMlike robots that could be cleverer than us.Can we continue to use these robots in a way that they serve us，or will they become so wise that they will want independence?
I am really not sure just how far scientists are going to perfect robots.But once this type of robot is made，they will be able to think，make decisions，sense the movement of others and decide what it wants to do.
A new invention has led to the introduction of a female robot，which was introduced at an entertainment show in Vegas.The robot called Roxy sells for bet
